To /f// lli/mm if ntrny/ concer/L:

Be it known that I, ARonni'rr O. (inassoo, a citizen ot' the UnitedStates, residingl in Hammond, in the county ot' Lake and State ofIndiana, have invented a new and useful Improvement in Machines VforAttaching' Stays to Iience-IVI'es. of which the following' is aspecilication.

This invention relates to improvements in tools t'or attaching wirestays to tence-wires, and is designed to be. used in the putt-ingltogether the tence shown in the Patent No.

615,260, granted to Frederick A. Curtis Def l cember t3, 1898.

The invention consists 1n the novel combinations ot' parts and devicesand in the novel 1 construction ot' parts and devices herein shown ordescribed.

The objectol' the invention has been to devise a i'nachine which willattach the stays lirmly, quickly and asily and which can be held in thehand and used as a hand-tool.

In the accompanying drawings, Vforming a part ot' this specitication,Figure 1 is a plan ot' the invention, showing it positioned ready tooperate. Fig. 2 is a partial plan of the invention at the conclusion ofthe operation.

I'eterring to the drawings, Il) Il) represent the Vtence strands orwires, and 11 one ot' the i The latter previous to its being upon theVtence-wires has its ends l tence-staysplaced doubled over so that thepoints stand parallel with the body portion, forming' hooks by which itmay be loosely caught on adjacent 'fencestrands preparatory to being'secured thereon by the machine or tool otl my present bolts 19.

i the bent portions ot' the stay.

I invention. This will be understood trom Fig.

9. The machine is intended to bend the points l 13 ot the stays so thatthey will completely l encircle the fence-wire, or, in other words, the

f machine closes the open hooks ot' the stays 50 upon the fence-wire,thereby making the attaclnnent both secure and permanent. The machiliealso t'orms a bend Il in the tencewire, adapted to prevent the stay fromslipping thereon, and it also t'orms the shoulder 55 l or bend 15 in thestay adjacent to the wire.

l The machine embodies a stationary forming-jaw, a movablet'Orming'-jaw,a trame-plate, and means for actuating the movable jaw.The trame-plate (shown at 16) has a flange I7 60 at its end, acting` asan abutmentagainst which thestationaryjaw leis positioned. Thisjaw is inthe form of a bridge arranged transversely l ot' the trame, to which itsends 5l) are bolted by It has a notch 20 on theactingside ot' 65 itscentral or raised portion intended to give room to the body portion ot'the stay, as seen at Figs. L) and 3, and its undersurface back ot' thenotch is recessed, as at QI, to give room to At each side ot' 70 thenotch its t'aces 5I are adapted to act as abutments to the tence-wire toresist the pressure by the movable jaw when it t'ornis the bend l1. Themovable jaw is formed on the end ol a slide Q2 and is provided with anacting tace 75 consisting' ol a rounded, inclined, andlorwardly-projecting portion '23, adapted to enter under the stationaryliaw, and a breast or vertical portion 'Z-t. a groove '25 heilig' formedin the parts 23 and 'Z-L, as seen plainly at Fig. SO

5, adapted to serve as a seat for the stay during the operation of themachine. This groove is preferably curved or tm'ned to one side, so itwill assist the pointotl the stay in assuming' a position in which itmay lap by the main 85 portion of the stay. The movable jaw is also iprovided with a projecting lip "26, adapted to i press against the bodyot' the stay a short dis l tance above the coiled portion. The slide relceives motion in closing the stay upon the 9 fence-wire from a pair oflevers 27 27, pivl oted at 28 28 and havingarms 29 29 engaging lshoulders 3() 30, formed on the rear end of l the slide. Aretracting-spring 31 draws the i slide back after each operation,spreading the l levers at the same time` and such spring encircles astem 32, attached to the slide, and is l confined on the stem betweenits head and a plate 33 at the rear of the frame 16. The slide isconfined at the sides between guides 34: 34 and at top by the plate 35,the latter being omitted from all the views except Fig. 3 for clearness.Stops 36 are employed to limit the opening movement of the levers.Blocks 37 are secured to the frame 16 and have overhanging edgesengaging the beveled side of the ends 50 of the stationary jaw, as seenin dotted lines at Fig. 3. These blocks assist by this engagement inholding the stationary jaw upon the plate.

`With the machine constructed as described the operation is as follows:The machine is positioned with the fence-wire lying transversely uponthe ends of the stationary jaw or upon the blocks 37, as seen at Fig. 1,and with the body of the stay in the notch 2O and with the hookedportion thereof resting in the lower portion ofthe groove 25. Power isnow applied to the slide, and the same is thereby urged toward thestationary jaw. This carries the incline 23 under the fencewires withthe stay in the groove 25, and gradually forces the fence-wire back orbeyond the plane of the abutment-surfaces 51. the bent portion of thestay moving along in groove 25 until it reaches the breast 2li. Thecontinued pressure or movement by the slide now carries the point 13until it closes the opening in the hook and securely holds thefence-wire. The bend 14 in the fence-wire is caused at the same time bythe fact that the fence-wire is held at each side of the stay by thesurfaces 51 of the stationary jaw, while the portion 14C is forced underthat jaw by the slide. The bend 15 in the stay is due to the fact thataportion of the coiled part of the stay is carried back of the plane ofthe notch 20. The body of the stay is prevented from tipping or yieldingto the pressure of the coiled portion thereof while the operation is inprogress by the lip 26, so that the formation described becomes a matterof certainty. '1n fastening the lower ends of the stays the frame isplaced under the fence-wire, and in fastening the upper ends it isplaced over the fence-wire.

In the modification shown at Fig. 6 I aim to facilitate the imparting ofthe lateral bend to the points 13. and to this end the shoulders 30 areplaced one in advance of the other instead of opposite each other, as inthe other construction: and the acting end of the slide is permitted aslight lateral movement by locating the guide 34 on the opposite side ofthe slide from the forward shoulder a short distance from the slide.lith this construction the lever acting' on the forward shoulder 30 willtend to force the acting end of the slide over against-the guidepositioned as stated, and thereby to carry the point 13 of the staylaterally.

The invention is intended primarily to be used by hand in attaching thestay to the fence-wires after the latter have been strung upon theposts; but it may be used in the manufacture of the fencing at thefactory.

I claim- 1. The combination in a machine for attaching hooked stays tofence-wires, of a stationary arch or bridge-like jaw notched on its faceto receive the stay, and a movable jaw consisting of the grooved incline23 and vertical breast 24, and acting to close the hook in the stay,substantially as specified.
